Research on Switching Control of DC Power Supply Interleaved Parallel Bidirectional DC/DC Converters

随着能源危机加剧,我国通过能源产业结构调整,扩大了新能源的研发及推广应用。为在高质量发展主题下持续推进节能减排,提高电力供给效率,应持续加强直流供电中的变换器切换控制研究。文章以此为出发点,概述了直流供电系统交错并联双向DC/DC变换器建模,剖析了双向DC/DC变换器控制方法。并在此基础上对切换控制策略与切换控制仿真内容进行了具体讨论。

With the intensification of the energy crisis,China has expanded the research and development,promotion and application of new energy through the structural adjustment of the energy industry.In order to continuously promote energy conservation and emission reduction under the theme of high-quality development and improve the efficiency of power supply,the research on converter switching control in DC power supply should be continuously strengthened.Based on this,this paper summarizes the modeling of interleaved bidirectional DC/DC converters in DC power supply systems,and analyzes the control methods of bidirectional DC/DC converters.On this basis,the switching control strategy and switching control simulation content are discussed in detail.
